Digging A Little Deeper
Science, Physics and math, along with spiritual and philosophical writings all point to a reality that is far different than the reality of what we see and believe we are interacting with.
Without getting into specifics, there is a large body of thought based upon the premise that we are replicating ecosystems, with identical foundations, going in and out, infinitely. This means that we as human beings are part of our ecosystem, have ecosystems within us and are part of larger ecosystems.
Given the knowledge we have in science and medicine, and using the premise of ecosystems referenced above, it is not a very far leap to agree with the authors conclusion.
I am going to use cancer as the example since most everybody understands this to a degree. In the simplest terms a cancer cell is a cell that has lost its ability to communicate (science has discovered that cells, bacteria, etc. speak languages and communicate). In doing so cancer replicates without regard to the body, its support system. Ultimately if cancer is not put in check, it kills the body. Our current most popular line of defense right now is to destroy the cancer cells in order to save the body.
Human beings are the cells in the body of humanity, and one of the many parasites that lives off of the earth. The earth, in essence, would then be considered an important component that is comprised of cells that makes up an organ or some other part of this larger body. So for discussion sake let's think of the earth as the liver of the larger ecosystems body.
We as human beings could very easily be considered a cancer to planet earth, as we multiply and destroy more and more of our supporting ecosystems.
Using the premise that the foundations of all ecosystems are identical (not in appearance but in structure) then it is not a far leap to believing that the destruction of the earth by human beings could be life threatening to this larger body, just as liver cancer would be life threatening to the human being.
This larger body may not have the ability to communicate directly to us, just as we do not have the ability to communicate with the cells and organs in our bodies (science is working on this too!).
When a human being's cancer reaches a certain point there are symptoms that send that person to the doctor, who in turn may order up chemo therapy. Similarly global warming may be a cancer symptom in the larger ecosystem and its doctor may order up it's version of chemo therapy:
"Destroy the cancer (human beings) to save the body."
